Two patches from 2022 (!), rediscovered now that Denis reinvented another
patch I had written but never tested (now commit cd3be3bd96c, "block/nbd:
clear reply.cookie under receive_mutex", 2026-09-02).

The first is just documentation, the second is an (at least theoretical)
race condition on s->reconnect_delay_timer.

Paolo Bonzini (2):
  nbd: comment on locking for requests[].coroutine
  nbd: call reconnect_delay_timer_del with requests_lock taken
